This widget class acts as a container for menu items similar to Tickit::Widget::Menu but displays them horizonally in a single line. This widget is intended to display long-term, such as in the top line of the root window, rather than being used only transiently as a pop-up menu.

This widget should be used similarly to Tickit::Widget::Menu, except that its name is never useful, and it should be added to a container widget, such as Tickit::Widget::VBox, for longterm display. It does not have a popup or dismiss method.

A single separator object can be added as an item, causing all the items after it to be right-justified.
